Usenza kanjani isibonisi se-LED sibe nencazelo ephezulu kakhulu

Umbukiso oholayo uthole ukunakwa okusabalele kusukela wazalwa. Ngokuqhubeka okuqhubekayo kobuchwepheshe bokufaka eminyakeni yamuva nje, iye yaqashelwa futhi yasetshenziswa ezimbonini ezihlukahlukene. Ukukhiqizwa nokugcinwa kokugcinwa kwesibonisi esiholayo nakho kudinga ulwazi lobungcweti. Ungasithola kanjani isibonisi esinencazelo ephezulu? Ukuze uzuze ukuboniswa okuphezulu, kufanele kube nezici ezine: okokuqala, umthombo wefilimu udinga i-HD egcwele; okwesibili, isibonisi sidinga ukusekela i-HD egcwele; okwesithathu, i-dot pitch yesibonisi se-LED sincishisiwe; futhi okwesine inhlanganisela yesibonisi se-LED kanye nephrosesa yevidiyo.
1. Ukuthuthukisa isilinganiso sokungafani sesikrini sokubonisa esinombala ogcwele we-LED kungenye yezinto ezibalulekile ezithinta umphumela wokubuka. Ngokuvamile, ukuphakama kwesilinganiso sokungafani, isithombe sicace futhi umbala ugqame. Ukugqama okuphezulu kusiza kakhulu ukucaca kwesithombe, ukusebenza kwemininingwane, nokusebenza kwe-grayscale. Kweminye imibhalo nevidiyo eboniswa ngokugqama okukhulu okumnyama nokumhlophe, isibonisi se-LED esinombala ogcwele esinokugqama okuphezulu sinezinzuzo ngokugqama okumnyama nokumhlophe, ukucijile, nobuqotho. Ukugqama kunomthelela omkhulu kumthelela wokuboniswa wevidiyo eguquguqukayo. Ngenxa yokuthi ukukhanya nobumnyama ezithombeni eziguquguqukayo kuyashesha uma kuqhathaniswa, lapho umehluko uphezulu, kuba lula emehlweni abantu ukuhlukanisa inqubo enjalo yenguquko. Eqinisweni, ukuthuthukiswa kwesilinganiso sokungafani sesikrini esinombala ogcwele we-LED ikakhulukazi ukuthuthukisa ukugqama kwesibonisi se-LED esinemibala egcwele kanye nokunciphisa ukubonakala kwesikrini. Kodwa-ke, ukukhanya akukona okuphakeme ngangokunokwenzeka, kuphezulu kakhulu, kodwa kuyoba okuphambene, kungagcini nje ngokuthinta impilo yesibonisi se-LED, kodwa futhi kubangele ukungcoliswa kokukhanya. Ukungcoliswa kokukhanya sekuphenduke isihloko esishisayo manje, futhi ukukhanya okuphezulu kuzoba nomthelela emvelweni nakubantu. Iphaneli ye-LED yesibonisi se-LED enombala ogcwele kanye neshubhu ekhipha ukukhanya kwe-LED kucutshungulwa okukhethekile, okunganciphisa ukubukeka kwephaneli ye-LED futhi kuthuthukise ukugqama kwesibonisi se-LED esinemibala egcwele.

2. Thuthukisa ileveli empunga yesibonisi se-LED esinombala ogcwele Izinga elimpunga lisho ileveli yokukhanya engahlukaniswa kusukela kokumnyama kakhulu kuye kokugqama kakhulu ekugqameni kombala owodwa kwesikrini se-LED esinombala ogcwele. Izinga elimpunga leIsibonisi se-LED esinombala ogcwele we-SandsLEDiphakeme. Uphakeme, umbala ucebile, umbala ukhanya kakhulu; ngokuphambene, umbala wokubonisa awuwodwa futhi ushintsho lulula. Ukuthuthukiswa kwezinga elimpunga kungathuthukisa kakhulu ukujula kombala, ukuze izinga lokubonisa lombala wesithombe likhule ngokwejometri. Ileveli yokulawula umbala ompunga we-LED ngu-14bit~16bit, okwenza imininingwane yeleveli yesithombe nemithelela yokubonisa yemikhiqizo yesibonisi ephezulu ifinyelele ezingeni eliphezulu lomhlaba. Ngokuthuthuka kobuchwepheshe behadiwe, isikali esimpunga se-LED sizoqhubeka nokuthuthuka siye ekunembeni okuphezulu kokulawula.

3. Ukunciphisa ukuphakama kwechashazi lesibonisi se-LED esinombala ogcwele Ukuncipha kokuphakama kwechashazi lesibonisi se-LED esinemibala egcwele, kwenza isibonisi sesikrini sibe sithambile. Nokho, leli phuzu kufanele lisekelwe ubuchwepheshe obuvuthiwe. Izindleko zayo zokufaka zinkulu uma kuqhathaniswa, futhi intengo yesibonisi se-LED esinemibala egcwele ekhiqiziwe nayo iphezulu. Ngenhlanhla, imakethe manje ithuthukela ekubonisweni kwe-LED ene-pitch encane.

4. Inhlanganisela yesibonisi sesikrini esinombala ogcwele we-LED kanye nephrosesa yevidiyo Iphrosesa yevidiyo ye-LED ingasebenzisa ama-algorithms athuthukisiwe ukuze iguqule isignali ngekhwalithi yesithombe esingesihle, yenza uchungechunge lokucubungula olufana nokususa ukuhlanganisa, ukulola unqenqema, isinxephezelo sokunyakaza, njll. , ukuthuthukisa ikhwalithi yesithombe. imininingwane futhi uthuthukise ikhwalithi yesithombe. I-algorithm yokucubungula isikali sesithombe sephrosesa yevidiyo isetshenziswa ukuze kuqinisekiswe ukuthi ngemva kokukalwa kwesithombe, ukucaca kanye nezinga elimpunga lesithombe kugcinwa ngokwezinga elikhulu. Ngaphezu kwalokho, iphrosesa yevidiyo nayo idinga ukuba nezinketho ezicebile zokulungiswa kwesithombe nemiphumela yokulungisa, futhi icubungule ukukhanya kwesithombe, ukugqama, kanye nesikali esimpunga ukuze kuqinisekiswe ukuthi isikrini sikhipha isithombe esithambile nesicacile.
